Existing CNN models generally rely on increasing depth to model such relations which is highly inefficient. In this work, we propose the \"double attention block\", a novel component that aggregates and propagates informative global features from the entire spatio-temporal space of input images/videos, enabling subsequent convolution layers to access features from the entire space efficiently. The component is designed with a double attention mechanism in two steps, where the first step gathers features from the ","authors_text":"Jianshu Li, Jiashi Feng, Shuicheng Yan, Yannis Kalantidis, Yunpeng Chen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-10-27T02:32:22Z","title":"$A^2$-Nets: Double Attention Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.11579","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:d24c5120e557c4319f919c22c41df23412d980f09219f002707c9e6c2aa22e6b","target":"record","created_at":"2026-05-18T00:02:08Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"0d88a102e4a0b5a8d36a0274886f2ed09061991e2562f16a31e769e3b7d58c6c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-10-27T02:32:22Z","title_canon_sha256":"fe3e3ab84a86d2d1b4f393d6c128635a65d087dba4ba517c5fc46c4b6ad64d19"},"schema_version":"1.0","source":{"id":"1810.11579","kind":"arxiv","version":1}},"canonical_sha256":"94eada995601c005f838f458f7df87c53774761cdabbefaa604cc20fc8228418","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"94eada995601c005f838f458f7df87c53774761cdabbefaa604cc20fc8228418","first_computed_at":"2026-05-18T00:02:08.196181Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:02:08.196181Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5XCyltFwWtcXqDyHB9JEzATpuYuJ//45Hk+lKCU/46i1jMJVxvSk9RXspM8sFJnw8y/UhpijGZCK45l8MritDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:02:08.196953Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.11579","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d24c5120e557c4319f919c22c41df23412d980f09219f002707c9e6c2aa22e6b","sha256:4ed6f1128a31b5e4f111f4eed185bd85d806618a569f561836d0264707a60517"],"state_sha256":"bd6c2c724ceec3e2bd1abc12781cd6d3c02ea8dcc52e9d6429683bf2708237c6"}
